The Oil Level Transmitter is located on the front of the separator near the bottom/center. See Figure 52.

The linear transmitter with hermetic enclosure is based on the capacitive measuring principle.

It features removable electronics (from the sensor well) eliminating the need to evacuate the compressor for replacement. This transmitter is dedicated to oil level control and has no user adjustments.

Remove DIN connector plug from transmitter.

WARNING: Do not mix oils of different brands, manufacturers, or types. Mixing of oils may cause excessive oil foaming, nuisance oil level cutouts, oil pressure loss, gas or oil leakage and catastrophic compressor failure.
